A kind of cassava residue culture medium and preparation method thereof

Abstract

The invention discloses a cassava slag culture medium and a preparation method thereof, relates to technology of biological enzymolysis, and belongs to the field of secondary utilization of energy. The culture medium is characterized by being composed of following components in percentage by weight: 80 to 85% of cassava, 12 to 15% of leaf mold, 1% of brown sugar, 1 to 5% of peat, 1 to 5% of moss, and water, wherein the mass ratio of materials to water is 1:1.3 to 1.5. The culture medium has the advantages of looseness, fertility, small soil bulk density, strong water discharging performance and air permeability, and strong water and fertilizer preservation performance, comprises a large amount of nutrition elements and micro nutrient elements, which are essential during the flower growth process, has a long effective period and no disease or insect source, and is especially suitable for being used as soils for breeding of precious flowers and replanting of seedlings.

Description

technical field [0001] The invention relates to biological enzymatic hydrolysis technology, belongs to the field of secondary utilization of energy, in particular to a cassava residue culture medium and a preparation method thereof. Background technique [0002] The long-term storage of cassava residues in my country leads to low utilization rate of cassava raw materials, occupation of land resources, and bad environmental impact. The situation is expected to change in the future. The new technology uses enzymatic hydrolysis technology, without the need of evaporation and concentration process, so that the extraction rate of residual starch from cassava residue can reach 90%, and the total sugar content in the extract can reach more than 130g / L. The cassava dregs produced from starch production are completely used in the production of cassava ethanol after pretreatment. Not only can almost all the residual starch in the cassava dregs be extracted, so that the starch resource...

AI Technical Summary

Problems solved by technology

[0003] Long-term storage leads to fermentation and corruption of cassava dregs, and the smell is pervasive, which not only reduces the utilization rate of cassava raw materials, but also occupies valuable land resources and has a bad impact on the surrounding environment

In addition, in traditional processing methods, in addition to a large amount of cassava residues that are difficult to utilize, a large amount of wastewater containing organic matter such as starch degradation products, protein, and soluble ash is also generated during the production process. many resources

[0004] Placing lush flowers and plants in the living room is not only a good decoration, but also plays a certain role in improving the temperature, humidity, and air quality of the local environment. However, the pot soil in the flower pots often emits an unpleasant smell, especially when applying flower fertilizer After that, small bugs will also breed. Therefore, the development of a culture medium suitable for flowers is a sign that modern people need a high-quality life
